A wrong-way driver was stopped and arrested on a Phoenix-area freeway early Friday morning by state troopers and Phoenix police.

No collisions or injuries were reported. Authorities suspected impairment to be a factor.

The car was initially reported to be headed northbound in the southbound lanes of State Route 51.

Trooper Kameron Lee, a spokesman for the Arizona Department of Public Safety, said a Phoenix motor officer found and stopped the vehicle as troopers performed a traffic break to move other vehicles to the right side of the road.

The driver was finally stopped on the Loop 101 near Scottsdale Road.

The driver was taken by state troopers to a Phoenix police station to continue the investigation, Lee said.

It was the first wrong-way driver reported on Valley freeways so far in 2018.
